The reading app your AI can read.

Read. Mark. Let your AI pick it up.

Works with Claude, ChatGPT and Perplexity — on your accounts, your credits, your chat history.

• Highlight with your Pencil

  Mark passages in PDFs and Markdown the way you would on paper — six colours, notes on any mark.

• Your AI reads your marks

  Connect Claude, ChatGPT or Perplexity in two minutes. It sees your documents, highlights and notes — and replies in threads under your marks.

• Send documents from chat

  Ask your assistant to send a report, paper or draft to your library. It appears on your iPad, ready to read.

• Whole library offline

  Everything you keep is readable on the plane. Changes sync when you're back.

• Your docs stay in your vault

  We never send your content to any AI company. Your assistant connects to us, with a key only you can create — and revoke.

• Built for reading at night

  Proper dark mode across every screen, because reading happens after hours.
